month, and all these leaves were coloured red, making the tree very 
conspicuous, there being no other one like it. This year the tree is not 
to be distinguished from the others. Evidently the leaves which 
appeared when the light of the sun was too strong were protected by 
the red colouring matter. 
That a few young shoots of an oak contain this pigment in their 
leaves can be observed every year at the beginning of summer, but that 
all the leaves of a tree should be coloured in this way is an exceptional 
and very significant occurrence.

Mr. PERINGUEY exhibited examples of the so-called ‘jumping eggs.’ 
Unlike specimens found in the vicinity of Cape Town, these galls were 
not found on the leaves, but on the stems of a species of Rhus. The 
examples exhibited were received from Riversdale, and were produced
